Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
JSON.parse(jsonString)
Why it's wrong here
JSON.parse is not a valid method name in the Salesforce JSON class.
- ✓
(List<Account>) JSON.deserialize(jsonString, List<Account>.class)
Why this is correct
JSON.deserialize requires the JSON string and the target type token (.class) to cast the result correctly.
- ✗
List<Account>.parse(jsonString)
Why it's wrong here
Collections do not have a parse method for JSON conversion.
- ✗
JSON.deserializeUntyped(jsonString)
Why it's wrong here
deserializeUntyped returns untyped maps and lists rather than a strongly typed List<Account>.
